CARE AND CLEANING
To keep your Del Rey Heater in maximum performance, we recommend the following to be perform
annually.
1. With an air hose regulated to 30 psig, blow off any dust and dirt that has accumulated
around the burner and inside the control compartment of the heater. Proper eye protection
required.
2. From the front of the heater, direct the air hose from a distance of approximately 12 inches
over the entire exposed area of each burner's ceramics.
3. Do not insert air hose into the inlet of the burner.
4. Remove main burner orifice, clean and re-install.
5. Check to insure heater is securely mounted and the clearance from combustible materials
is maintained.
6. If additional service to the heater is required contact your local dealer or the factory.
BEFORE CALLING FOR SERVICE – BASIC TROUBLESHOOTING
If no glow from hot surface igniter:
a) Check power supply, should have 24 volts between power wires. Use volt meter between
inlet wire and ground terminal inside heater control box to measure 24 volts.
b) Check continuity by using an ohmmeter. Check resistance between valve wire and ground.
Ohmmeter should read almost no resistance or (# ohms) through valve. If high resistance,
check wire connectors.
c) Be sure connectors are fully inserted into ignition control.
If insufficient gas flow:
a) Manual gas valve not fully to “ON” position. Turn valve handle to full “ON” position. Also
ensure internal lever is in the “ON” position (as shown on page 11).
b) Burner orifice plugged. Remove service panel, remove burner orifice (7/16” wrench) and
thoroughly clean. Insects may crawl into orifice hole and block the orifice.
